WinRider, did you get more range with the correction? Or you have the same?

I did not ride it much for range after that last update before I sold it.   But I do remember on the last ride it seemed to go forever so it may have helped with range as well but I can not say it was scientifically proven.

I noticed the "hunting" when trying to hold a constant speed on level pavement with my 2010 DS. I have not seen it with either my 2012 DS or 2013 FX. I attribute that to the later bikes being a completely different motor and controller system.

I had forgotten about this until I recently rode my 2010 after more than two years of not riding it. It was annoying. I also had forgotten how much better the newer Zero bikes handle. The geometry has improved.

Thanks for the input.

I called my local dealer and informed him of the issue. They will discuss with Zero about how to check and calibrate the encoder. If everything is OK with them, I will have my bike checked at the same time than for the recall, which they don't have the tools yet.

Speedometer inaccuracy is also an issue with mileage-based warranties. If your speedo is 5% optimistic, you're getting to the end of your warranty 5% early.

My bike is getting worse in constant speed. It has been noticeable only for last couple of thousand miles or the 4K covered. I have been thinking it might have been water getting into connectors as I haven't really had a dry ride since October. Spraying everything with ACF-50 has reduced weird behaviour of the dash with no effect to hunting. Good to hear that I'm not alone. Would be great have dealer to go to. The last one in the UK ceased trading end of December so I seem to be well stuck with what I've got.

This is a good point, but not true on the bikes I've ridden. Often the odometer is driven from a much more accurate sensing mechanism than the speedometer.

I agree. Both of my BMW's have 8% fast speedometers, but the odometers seem quite accurate when measured against highway mile markers.  The trip meters are a little goofy though and don't match up with the odometer reading exactly.

Problem disappeared with the firmware update! The dealer told me that there was some type of calibration to do. That might have been the encoder calibration.

Speaking of speed calibration: yesterday I found a level piece of freeway and checked my instrument display (with my glasses on) and noticed that 60 mph shows 3850 rpm on my 2014 S.  Also, I was getting 85 watts per mile while holding my speed at a steady 60 mph on level ground with no wind.  I checked my speedometer against one of those radar speed check signs and an indicated 60 mph is an actual 59 mph.  That all sounds good to me.
